Our History

Christ Our Savior Lutheran High School was founded in 1999 when twelve congregations joined together to start a Lutheran high school in Randolph County. Classes were initially held classes at St. Peter’s Lutheran Church in Evansville, Illinois. Our first principal was Mrs. Sherry Prange. We started with just eleven students. Thanks to the generous giving of our association congregation members, we moved into a new gymnasium and multi-purpose building on August 8, 2004.  In 2008-2009, Mr. Ray Hill served as interim principal. Mrs. Ann Ryherd served as interim principal for the 2009-2010 school year.

On August 31, 2009, we dedicated our classroom building. John Christman served as our administrator from 2010-2016. Mr. Matthew Foster, who joined the staff at COSLHS in 2010, served as administrator from 2016-2023.  Mrs. Sherry Prange came back from retirement to serve as administrator in July 2023.

God continues to bless and provide for the ministry of Christ Our Savior Lutheran High School.
